You have found a new prokaryote. What line of evidence would support your hypothesis that the organism is a cyanobacterium? You have found a new prokaryote. What line of evidence would support your hypothesis that the organism is a cyanobacterium? It forms chains called mycelia. It lacks cell walls. It is able to form colonies and produce oxygen. It is an endosymbiont.

It is able to produce oxygen

Explanation:

The line of evidence that would support my claim is that the observed prokaryotes can produce oxygen. The cyanobacteria or the blue green algae are the only know prokaryotes that utilises photosynthesis which leads to the release of oxygen. Since it has already been established the discovered organisms is a prokaryote, it can then be confirmed that since this organism can produce oxygen, it is a cyanobacteria and that it also has features peculiar to the cyanobacteria

trachea, alveoli, lung capillaries, arteries
